1. Sometimes, a miniseries is just a miniseries. But the forces eager to turn “Big Little Lies” into a full-on series are growing. Based on Australian author Liane Moriarty’s novel, the show did well for HBO at an average of 7 million viewers per episode — better than “The Night Of.” Now, Moriarty, with support from star and producer Reese Witherspoon, is working on a plan for a second season: “The producers have asked me to see if I can come up with some ideas,” Moriarty told The Sydney Morning Herald. “I wouldn’t write a new book but perhaps a new story and then we’ll see what happens.” On the other hand, Jean-Marc Vallee, who directed the series so beautifully, told the Hollywood Reporter he’d rather not pursue more: “If there’s an opportunity to reunite with Reese, Nicole [Kidman], and these characters of course, I’ll be a part of it, but ‘Big Little Lies One’ is a one-time deal. ‘Big Little Lies Two’? Nah. . . . Why spoil it?”

2. The Cannes Film Festival has finally given in. For the first time, it’s going to include TV series during this year’s 70th event. The two featured shows are directed by former Palme d’Or winners. Jane Campion, who won for “The Piano” in 1993, will be there with “Top of the Lake: China Girl,” the second edition of her dark, atmospheric crime series. And David Lynch, who won for “Wild at Heart” in 1990, will accompany his new season of “Twin Peaks,” which is set 25 years after the events of the original. While other big film festivals, including Berlin, Venice, and Toronto, have already included TV, Cannes was a holdout. The festival runs May 17-28.

3. Hasan Minhaj, a “Daily Show” correspondent, will host this year’s controversial White House Correspondents’ Dinner on April 29. President Trump has said he will skip the event, making him the first sitting president since Ronald Reagan to miss it. Reagan couldn’t make the dinner after being shot, but he called in instead. “It is a tremendous honor to be a part of such a historic event,” Minhaj said in a statement, “even though the president has chosen not to attend this year. SAD! Now more than ever, it is vital that we honor the First Amendment and the freedom of the press.” By the way, SamanthaBeewill emcee another D.C. event called “Not the White House Correspondents’ Dinner” on the same night, as a benefit for the Committee to Protect Journalists.

4. Connie Britton left, but that’s not going to stop “Nashville.” The soap, which moved from ABC to CMT this year, has been renewed for a 16-episode sixth season. On CMT, the show has averaged 2.1 million viewers a week with delayed viewing factored in, a significant fall from its ABC days. CMT also announced that Jeffrey Nordling, who played Laura Dern’s husband on “Big Little Lies,” will join the cast.

5. David Letterman’s mother, Dorothy Mengering, died this week at 95. She was a regular guest on her son’s show for years, and she published a cookbook in 1996 called “Home Cookin’ With Dave’s Mom,” which included recipes such as “Dave’s Fried Baloney Sandwich.” About her appeal to Letterman’s viewers, Mengering told The New York Times in 1996, “I think it’s about the idea of mom and of a family. People are eager for families to be like they used to be. Even though there are lots of working moms and single-parent families now, you can still be a family in spite of the size and form it takes.”
